Description

This PIMORONI MAX30101 Breakout Heart rate Oximeter smoke sensor has three LEDs??green, red, and infra-red??and photodetectors that can be used together to detect the amount of light reflected back to the sensor. A technique called photoplethysmography (PPG) can be used to detect the change in color of your skin with each beat of your heart when the sensor is pressed against your fingertip.
You can use the MAX30101 to detect particles in the air, like smoke, by measuring the amount of light bounced back to the sensor by the particles. A rough example of how to do this in the Python library.
It??s also compatible with fancy Breakout Garden HAT, where using breakouts is?as easy as just popping it into one of the six slots and starting to grow your project, create, and code.
Note: This sensor (and the code in our Python library) should not be used for medical diagnosis, as the basis for a real smoke or fire detector, or in life-critical situations. It??s for fun/novelty use only, so bear that in mind while using it.
